Really enjoyed this book! The beginning started a little slow...I was overwhelmed with all of the characters being introduced and all of the technical stuff. But not too far in it all started to make sense and I was hooked. Lots of constant action - I've never read a book that had so many twists and things I didn't expect. When I thought it was coming to an end - Deaver threw a new twist at me I never saw coming. Very entertaining!
